I created Postwoman 👽 - An online, open source API request builder

- API request builder

Feel free to contribute on

In case you missed! Story this far: I joined , which is a start-up based in Kochi, Kerala where I work as a full-stack developer.

Story behind Postwoman: The very first task I was assigned is an API integration of an old project. That's when I came across . Postman has separate builds targeted to each operating systems made with Electron. I use a low-end PC and can't possibly afford to run another Electron app. From that moment onwards, I wanted to make an API testing platform which is:

- Open Sourced 💚

- Runs online

- Have multi-platform support

- Have multi-device support

- Accessible from anywhere

That's how was born (this is not at all an alternative to Postman - yet, it does the job very beautifully and minimally. It needs more features and love which I hope we all can ).

When I did a background check on API request builders, Postman offered various Plans & Pricing, there were lot of other API request builders based on CURL etc. But none of them seems simple, minimal and efficient.

That's why I created my own API request builder with pure JavaScript (I used Vue.js) + HTML + CSS 💖

Did I mention this service is all free of charge and 100% open source? Yes, It's free and always will be.
